Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method of forming a carrier tape used for taping and shipping a chip resistor, a chip capacitor, or other small electronic components, a carrier tape forming apparatus, and a small component. Regarding taping device.

[0002]

As is well known, small electronic components such as chip resistors and chip capacitors are shipped with taping. This taping work is performed in a series of steps as shown in FIG. 9, for example. That is, first, a desired small electronic component d is put into a plurality of window holes 10e provided in the long carrier tape body 1e at regular intervals,
Load it. Then, a cover tape 3e (top cover tape) having a heat-fusible adhesive layer 30 on one surface is provided on the upper surface of the carrier tape body 1e in the transport path of the carrier tape body 1e in which the electronic parts d have been loaded. Overlaid on. And after that, the cover tape 3e
By bringing the heated ironing surface 60 of the ironing member 6e into contact with the above, the cover tape 3e is adhered to the carrier tape body 1e through the adhesive layer 30.

[0003]

In the above taping work, the thin cover tape 3e is superposed on one surface of the carrier tape body 1e, and then the cover tape 3e and the carrier tape body 1e are ironed with each other.
When the cover tape 3e cannot be brought into close contact with one surface of the carrier tape main body 1e uniformly due to meandering of the cover tape 3e or slack of the cover tape 3e before being conveyed to the position was there. That is, conventionally, for example, as shown in FIG. 10, the center portion 38 in the width direction of the cover tape 3e is in a state of being raised more than the edge portions 39, 39 of the cover tape 3e, and the cover tape 3e is conveyed to the position of the ironing member 6e as it is, and the carrier member It may be adhered to the tape body 1e.

As a result, conventionally, the cover tape 3 has been used.
Since the window holes 10e of the carrier tape body 1e cannot be properly blocked by e, the electronic component d spills out of the cavity formed by the window holes 10e as shown by the phantom line in FIG. There were times when it ended up. This is not appropriate because the electronic component d cannot be properly protected and the electronic component d is likely to be damaged during the transportation of the carrier tape. Further, due to the occurrence of displacement of the position of each electronic component d, there arises a problem that it is difficult to handle when the taped electronic component d is taken out and used in the next process.

As means for solving the above-mentioned problems, the cover tape 3e superposed on the carrier tape main body 1e.
Apply a certain amount of tension to the cover tape 3
It is also conceivable to prevent the meandering and bending of e. However, in order to completely prevent the soft and thin cover tape 3e from bending, a considerably large tension is applied to the cover tape 3e.
Need to be given to. Therefore, with the above-mentioned means, a problem that the cover tape 3e is often broken due to the tension occurs, and it is difficult to appropriately eliminate the above-mentioned inconvenience. In particular, when a narrow paper tape is used as the cover tape 3e, the cover tape has a very high frequency of breakage, resulting in deterioration of workability.

The present invention has been devised under such circumstances, and the cover tape is adhered to the carrier tape body in a raised state without causing a trouble such as breakage of the cover tape. It is an object of the present invention to solve such a problem by a simple means and prevent the small parts to be taped from protruding.

[0007]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

That is, according to the first aspect of the present invention, a step of conveying a carrier tape body having a plurality of window holes provided at predetermined intervals, and a step of feeding the carrier tape body close to a conveying path of the carrier tape body. And a step of adhering the cover tape and the carrier tape body, which are superposed on each other and conveyed, by a guide means so as to superpose the cover tape on the carrier tape body. A method of forming a carrier tape in which a hole is formed as a cavity for accommodating a small component, wherein a tape holder provided in the guide means is provided between the time when the cover tape is superposed on the carrier tape body and the time when the both are adhered. Characterized in that the cover tape is pressed along the carrier tape body by means. That.

According to the second aspect of the present invention, the carrying means for carrying the carrier tape body provided with a plurality of window holes at predetermined intervals, and the carrier tape body carried by the carrying means are brought close to each other. An apparatus for forming a carrier tape, comprising guide means for guiding the supplied cover tape so as to be superposed on the carrier tape body, and adhesive means for adhering the cover tape and the carrier tape body which are superposed on each other. The guide means is provided with a tape pressing means for pressing the cover tape superposed on the carrier tape main body so as to follow the carrier tape main body.

According to a third aspect of the present invention, there is provided a taping device for small parts, wherein the cover tape is superposed on the carrier tape main body in the carrier tape main body conveying path in the above-mentioned carrier tape forming apparatus. It is characterized in that a component loading means for loading a desired small component is provided in a window hole having an upper surface opening at a position upstream of the position.

According to the present invention, the cover tape is forced onto the surface of the carrier tape body by the tape pressing means between the time when the cover tape is superposed on the carrier tape body and the time when the cover tape is adhered to the carrier tape body. Since it can be pressed down, unlike the conventional case, even if a large tension is not applied to the cover tape, the center part of the cover tape in the width direction is undesirably raised from the carrier tape body. Can be eliminated. That is, in the present invention, the entire cover tape can be brought into close contact with the carrier tape body in a substantially uniform state, and then the cover tape is adhered to the carrier tape body while the center portion in the width direction is raised. Can be eliminated.

Therefore, in the present invention, unlike the prior art, the opening of the window hole of the carrier tape body can be appropriately closed by the cover tape, and the small parts housed in the window hole are exposed to the outside of the window hole. It is possible to prevent improper protrusion. As a result, it is possible to properly protect the taped small parts, and to improve the workability when handling the taped small parts in the next work process. Of course, since it is not necessary to apply a large tension to the cover tape, it is possible to appropriately avoid the disadvantage that the cover tape is frequently broken during the operation of forming the carrier tape.

Further, in the present invention, since the tape holding means is provided in the guide means for guiding the cover tape, it is not necessary to support the tape holding means separately from the guide means, and the tape is used. The advantage is that the device configuration for mounting and holding the pressing means at a predetermined position can be simplified. Furthermore, when the cover tape is guided by the guide means so as to overlap the carrier tape body, the cover tape can be immediately pressed by the tape pressing means provided in the guide means. Therefore, it becomes possible to more thoroughly prevent the slack of the cover tape and the like, and it is also possible to obtain an effect that the cover tape can be adhered to the carrier tape body in a good condition.

In a preferred embodiment of the present invention, the guide means is composed of a fixing member having a groove for inserting the cover tape so as to regulate the position of the cover tape in the width direction. In the tape pressing means, the pressing surface contacting the cover tape is substantially flush with the guide surface of the guide means facing the carrier tape body, and extends in the same direction as the carrier tape carrying direction. The configuration can be set.

With such a structure, the cover tape can be prevented from meandering by inserting and guiding the cover tape in the groove portion of the guide means constituted by the fixing member. Also, the pressing surface of the tape pressing means is
Since it is set so as to extend in the same direction as the conveying direction of the carrier tape body in a state of being substantially flush with the guide surface of the guide means facing the carrier tape body, the guide surface of the guide means causes the surface of the carrier tape body to face. It is possible to press the cover tape guided by the tape directly to the surface of the carrier tape body by the pressing surface of the tape pressing means, and it is possible to reliably prevent the cover tape from floating from the carrier tape body. Therefore, there is an advantage that the adhesiveness of the cover tape to the carrier tape body can be further improved.

[0016] In another preferred embodiment of the present invention, the adhering means is an iron for heating a heat-fusible adhesive layer provided on one surface of the cover tape in contact with the carrier tape body. The iron member may be provided with a surface, and the iron surface of the iron member may be provided with a recess corresponding to the window hole of the carrier tape.

According to this structure, the cover tape is applied to one surface of the carrier tape body by pressing and heating the heat-fusible adhesive layer provided on one surface of the cover tape with the iron surface of the iron member. It can be bonded, but since the iron surface has a recess,
No pressing heat is applied to the window hole forming portion of the carrier tape body by the iron member. Therefore, even when a small component such as an electronic component is housed in the window hole forming portion, the small component is not thermally damaged by the iron member, and proper taping can be performed.

Further, in another preferred embodiment of the present invention, in the carrier tape forming apparatus using the ironing member, the tape pressing means is located in the recess of the ironing surface of the ironing member from the position of the guide means. It can be configured to be extended to the position of.

According to this structure, the cover tape and the carrier tape body can be adhered to each other by the iron member while the cover tape is pressed against the surface of the carrier tape body by the tape pressing means. Therefore, it is possible to more thoroughly prevent the cover tape from being adhered to the carrier tape body while the center portion in the width direction of the cover tape is unduly raised.

A pin for inserting the pin into is properly provided. In addition,
The drive roller 4a performs intermittent rotation so as to intermittently convey the carrier tape body 1 and the other cover tapes 2 and 3.

The first guide body 8A is a winding roller R2.
It is for guiding the bottom cover tape 2 fed out from above so as to overlap with the one surface 1a of the carrier tape body 1. Therefore, this first guide body 8A
May be constituted by, for example, a fixed member that is not rotatable, or may be configured as a driven rotatable roller.

As shown in FIG. 5, the first ironing member 6A is guided by the first guide member 8A to heat the bottom cover tape 2 superposed on one surface 1a of the carrier tape body 1 to heat the carrier tape body. 1 for thermocompression bonding. When the bottom cover tape 2 is bonded to the carrier tape body 1, a small component d is still placed in the window hole 10 of the carrier tape body 1. In the case of bonding the top cover tape 3 described later. Unlike the above, heating the entire one surface 2a of the bottom cover tape 2 does not cause any inconvenience.

Therefore, the ironing surface 60A heated by the built-in heater of the first ironing member 6A is
For example, it is formed as a flat surface that can come into contact with the entire surface of one side of the bottom cover tape 2. The first ironing member 6A is fixedly provided, and the bottom cover tape 2 superposed on the carrier tape body 1 is set to be conveyed while slidingly contacting the ironing surface 60A. A backup member 65A for appropriately performing thermocompression bonding by the first ironing member 6A is appropriately provided at a position facing the first ironing member 6A.

As shown in FIG. 2, the component loading device 7 is for loading a desired small component d such as a chip resistor or a chip capacitor into the window hole 10 of the carrier tape body 1. The component loading device 7 is synchronized with the transport mechanism of the carrier tape main body 1 so that the small component d is loaded into the window hole 10 of the carrier tape main body 1 that is intermittently transported during the transport stop period. It is set.

The second guide body 8B has a winding roller R3.
It is for guiding the top cover tape 3 fed out from the carrier tape body 1 so as to be superposed on the upper surface 1b of the carrier tape body 1, and is provided at a stage subsequent to the component feeding device 7 (downstream side in the tape feeding direction). ing. As described above, the tape pressing body 5 is attached to the second guide body 8B, and the specific configuration thereof is as shown in FIGS. 6 and 7, for example.

That is, in each of these figures, the second
The guide body 8B has a block shape or a roller shape having a horizontal through hole 80, and a groove portion for fitting the top cover tape 3 into a front surface portion at a substantially central portion in the longitudinal direction thereof. 81 is provided. Also,
A vertical guide surface 8 for guiding the top cover tape 3 is provided at and near the location where the groove 81 is formed.
2 and a substantially horizontal guide surface 82a are formed. The second guide body 8B is formed by inserting an appropriate supporting means (not shown) into the through hole 80, and the like.
It is fixedly provided at the upper position of the transport path.

The tape pressing body 5 is formed in a long and thin form in which a flat pressing surface 50 is formed in series on the lower surface thereof, and the front end portion of the tape pressing body 5 is provided with a bolt 51 through the above-mentioned structure. It is fixedly attached to the rear surface portion of the second guide body 8B. However, when attaching the tape pressing body 5, the pressing surface 50 is substantially flush with the substantially horizontal guide surface 82a of the second guide body 8B,
Further, it is set so as to extend in the same direction as the carrying direction of the carrier tape body 1 (horizontal direction in this embodiment).

In FIG. 1 and FIG. 2, the second ironing member 6B is for thermocompression bonding the top cover tape 3 superposed on the one surface 1b of the carrier tape body 1 to the carrier tape body 1. Like the first ironing member 6A, the second ironing member 6B has an ironing surface 60B heated by a built-in heater at its tip end surface.
B is configured so as not to heat the window hole 10 portion of the carrier tape body 1.

That is, below the second ironing member 6B, the small component d has already been put into the window hole 10 of the carrier tape body 1, and the portion of this window hole 10 is made into the second hole.
If the iron member 6B is used for heating, the small component d is thermally damaged, or the top cover tape 3 and the small component d are heated.
There will be a problem such that the and will bond improperly. Therefore, the second iron member 6B does not heat the portion of the window hole 10 of the carrier tape body 1.

Specifically, as shown in FIG. 3, this second
A portion of the ironing member 6B corresponding to the window hole 10 of the carrier tape body 1 is configured as a recess 61 having no ironing surface. Therefore, this second
The ironing member 6B has a pair of left and right ironing surfaces 60B, 60B which are spaced apart from each other by a predetermined distance. Further, the second ironing member 6B is provided so as to be able to move up and down by means of a reciprocating motion device such as a reciprocating cylinder 62, and descends during a period in which the carrier tape body 1 which is intermittently conveyed is stopped from feeding, and the top cover tape 3 is set to be pressed and heated. Further, a backup member 65B is fixedly provided at a position facing the second ironing member 6B.

The tape retainer 5 is extended so that its rear portion enters the recess 61 of the second iron member 6B.

Next, an example of a taping method for small parts which employs the method for forming a carrier tape according to the present invention using the taping device having the above-mentioned structure will be described.

First, as shown in FIGS. 1 and 5, in the process of transporting the carrier tape body 1 unwound from the winding roll R1, the bottom cover tape 2 unwound from the winding roll R2 is superposed. Further, this bottom cover tape 2 has one surface thereof which is superposed on the carrier tape body 1 and one surface thereof being the ironing surface 60 of the first ironing member 6A.
Sliding contact with A. Thereby, the heat-sealable adhesive layer 20 provided on the one surface 2a of the bottom cover tape 2 is formed.
Can be melted and softened, and the bottom cover tape 2 can be bonded to one surface 1a of the carrier tape body 1 via the adhesive layer 20. Therefore, the opening on one end side of each window 10 of the carrier tape body 1 can be closed, and this window 10 can be formed as a cavity for accommodating a small component.

Next, as shown in FIG. 2, the carrier tape body 1 to which the bottom cover tape 2 is adhered is then intermittently conveyed to a position below the component loading device 7. Then, during the period during which the carrier tape body 1 is stopped,
A desired small component d is put into the window hole 10 and accommodated therein.

After the small parts d are loaded, the top cover tape 3 is placed on the one surface 1b of the carrier tape body 1.
Overlap. This superposition is performed by the guide transfer of the top cover tape 3 along the guide surfaces 82, 82a of the second guide body 8B. The top cover tape 3 is formed on the second guide body 8B described in FIG. If the top cover tape 3 is fitted and held in the groove 81, it is possible to prevent the top cover tape 3 from wobbling in the width direction and meandering. Further, the central portion in the width direction of the top cover tape 3 which has passed through the guide surface 82a can be pressed downward by the pressing surface 50 of the tape pressing body 5 which is set substantially flush with the guide surface 82a. . Therefore, the top cover tape 3 passed through the second guide body 8B and superposed on the carrier tape body 1
It is possible to prevent the central portion in the width direction from being unduly raised.

In particular, since the tape pressing body 5 is extended so as to enter the concave portion 61 of the second iron member 6B, the top cover tape 3 is also located below the second iron member 6B. It is possible to prevent the center portion in the width direction from rising, and the top cover tape 3 can be placed along the carrier tape body 1 in a flat state.

Therefore, when the second ironing member 6B in the state shown in FIG. 2 is lowered and both side edges 31, 31 of the top cover tape 3 are pressed and heated by the ironing surfaces 60B, 60B, the top cover tape 3 is unjustified. Both side edges 31, 31 of the top cover tape 3 can be adhered to the carrier tape body 1 via the adhesive layer 30 without forming a swelling state. As a result, it is possible to perform taping in which the opening of the window hole 10 of the carrier tape body 1 is surely blocked, and the small component d in the cavity formed by the window hole 10 protrudes from this cavity. Can be appropriately prevented. The carrier tape, which has been taped as described above, has a winding roll Ra shown in FIG.
As shown in, it may be rolled up in order.

In the above embodiment, the tape retainer 5 is attached only to the second guide body 8B, and the tape retainer is not attached to the first guide body 8A. This is the flat ironing surface 6 of the first ironing member 6A.
Since the entire surface of the bottom cover tape 2 is in sliding contact with 0A, the central portion in the width direction of the bottom cover tape 2 is unlikely to rise, and it is not always necessary to use a tape pressing body. However, the present invention can also be applied to the case where the bottom cover tape 2 is superposed and adhered to the carrier tape body 1. Therefore, for example, as a means for adhering the bottom cover tape 2 and the carrier tape body 1 to the first guide body 8A, the same means as the means for adhering the top cover tape 3 and the carrier tape body 1 is adopted. A tape pressing body having the same structure as the tape pressing body 5 may be provided.

Further, in the above-mentioned embodiment, the openings on both sides of the carrier tape body 1 having the window 10 penetrating therethrough are closed by the bottom cover tape 2 and the top cover tape 3, but the present invention is not limited to this. Not done. In the present invention, for example, as shown in FIG. 8, a carrier tape main body 1 made of synthetic resin in which a large number of bottomed windows 10A are formed.
The top cover tape 3 may be superposed and adhered to only one surface of the carrier tape body 1A by using A.

Further, in the above embodiment, since the tape pressing body 5 is extended to the position where it is inserted into the concave portion 61 of the iron member 6B, the carrier in the state where the widthwise central portion of the top cover tape 3 is raised. Tape body 1
However, the present invention is not limited to this. In the present invention, the tape pressing body may be provided only up to a position before the iron member. Even in such a case, it is possible to significantly reduce the swelling of the widthwise central portion of the cover tape as compared with the conventional case.

In addition, the concrete construction of each part of the carrier tape forming device and the taping device for small parts according to the present invention can be variously changed in design. The carrier tape forming apparatus according to the present invention does not necessarily have to be configured as a built-in taping apparatus for taping small parts. It may be configured as a device for forming and manufacturing a carrier tape for taping parts.
Similarly, the specific contents of each step of the method for forming a carrier tape according to the present invention can be changed in various ways. Of course, the present invention is not limited to specific types of small parts to be taped.
